ABSTRACT:
A container (10) for carrying bulk materials includes a body portion (12) having an open top, a cover (11) to close the open top, and a base portion (13) holding the body portion. The base portion (13) has sidewalls (39) which cradle the sidewalls (25) of the body portion (12), which sidewalls (25) are tapered so that the container (10) can be nested within a like container. Material to be discharged from the container may pass through a valve (33) positioned in a recess (32) in a sidewall (25) of the base portion (12). A preferably flexible liner (14) may be received in body portion (12) and includes a peripheral cuff (46) for attachment to the cover (11) and base portion (12). The liner (14) also has a tube (44) which can communicate with the valve (33) for discharge of the material from the liner (14). The container (10) is made of a resulting translucent plastic formed from the reaction of an isocyanate and a polyol resin utilizing a process whereby pressure is applied to the tanks (58, 60) holding the reactant material (58) and the resin material (60) only during the time when the materials (58, 60) are being transported to the mold (67).
